Procedure
To a solution of 4-(5-bromo-2-hydroxy-3-methoxy-benzyl)-piperazine-1-carboxylic acid phenylamide (1.2 g) in Et2O (16 mL) was added HCl (2 M in Et2O, 3.5 mL). After 1 h, the mixture was concentrated to give the title compound as a white solid. 1H NMR (400 MHz, CD3OD): 7.40-7.20 (m, 6H), 7.10-7.05 (m, 1H), 4.37 (s, 2H), 3.94 (s, 3H).
